Application filed June This invention relates to jail door looking mechanismparticularly adapted for appl cationjto the jail doors of a row, of ]a1l cells, the locking'mechanism of eachdoor being controlledfro n a common point from which the doors of the row may be selectively and I positively locked, unlocked, opened or closed.

'The invention comprises generally improvements upon the locking mechanism set forth indetail my Patent 1,543,140, of June 23, 1925, to which reference may be had for features "referred to herein merely ina generallway.

Specifically this invention has'for its 0bjec t, the provision of additional means for securing the door or doors automatically in ilos'ed or open positionand yet for selectively releasing such of the doors as it is desired to move. r

Referring now to the drawings, Fig. 1 shows a jail door and portion of a similar door of an adjoining cell in closed position, together with acoinplete. unit for the manipulation thereof; Fig. 2 is a detail of the mechanism with the door in closed position the lock having just been'released; Fig. 3 is a similar detail but vwith the door locking in fully open position;- Fig. 4 is a section alongthe line 44 of Fig. 3; Fig. 5 is a sec tionalong the line 55, Fig] 3, and Fig. 6 is adetail in elevation of a' portion of the control panel, showing two of the control levers.

7 Reference numerals in the drawings correspond'in so far as possible vwith those ap- V pearing in the above designatedpatent.

When it is desired to close the door illustrated, the lever 40 is moved upwards to the locked position, lowering the bolt 98 to an elevation to enter the notch 100 in the gap nut in which position the dog- 50l'is clear of the detent 503; Thereupon to positively close the door it is "merely necessary to move the gap nut to the right sufliciently to engage the wedge bolt and then return the gap nut, and the door with it to closed position.

Movable with the door and secured upon one of the side plates 9 is an upwardly extending finger or abutment 502, its upper extremity being bent as appears in Fig. 4 to the plane of the detent member 504. As

' the door reaches closed position the detent 504 being of the proper length is engaged by it and drops behind the finger 502, to lock the door inthisposition.

WVhen the lever 40 is again moveddownward to unlock the door, the upward motion of the bolt 98 carrying the dog 501 raises the detent 504 to clear the finger 502, whereupon the door may be moved to open position as described.
